GOLLAPSIBLE BAG FRAME.

Application filed January 22, 1926. Serial No..82,943.

The improvements generally consist of a multi-membered frame composed of a plurality of like parts hingedly connected at their ends, whereby all of the several frame members are maintained in the same plane irrespective of being in an open or closed condition.

A further invocation resides in the structure and arrangement'of the hinge elements, which are so devised as to facilitate polishin and like operations, and avoid damage being done to the frame while undergoing such operations, to which frames of ordinary t pes are commonly subject, resulting in loss ue to spoilation of the same.

It is another feature to provide a frame composed of bar-like members arranged in symmetrical relation, an equal number of members being disposed on each side and which may be closed in parallelism or spread to form open hexagonal, octagonal or other shaped frames, giving the fullest possible area of opening to the bag, means also beln provided to hold the frame when in closed position. 7

These and sundry other practical advantages are accomplished by the novel construction, combination and arrangement of parts later on described in detail and shown in the drawing relating hereto and in which Figure 1 is a perspective view of an embodiment of the invention, showing the frame in closed position.

Figure 2 is a perspective view of the frame element joints prior to engagement, drawn to an enlarged scale.

Figure 3 is apartial top plan, partial sectional view taken on line 3--3 of Fig. 5, be-

fore final closing of the joint elements.

Figure 4 is a similar view of the same, showing the parts closed.

Figure 5 is a front elevational view of the frame at one of its joints.

As shown in the drawing, the frame-is composed of several pairs of similar bar elements, 10, 10, 11, 11 and 12, 12, which may be formed of sheet metal in the usual channel shape, it bein understood that the material of the bag 18 eventually secured within the channels.

The adjacent walls of the end elements are extended and curled to produce hinge eyes 13 connected by pivots 14 to allow t 9 in an open position.

011 h in ed a bar 1 is ar anged a spring actuated clip 15 adapted to engage over a pin fixed in the mating member 11 in the ordinary manner, the clip being provided with an extending ledge 17 for convenience of operation.

The invention resides more particularly in the joints between the intermediate and end bar members which will now be described.

The inner and upper walls at the adjacent ends of the channel bars are cut squarely across and the outer walls extended, as at 18, 19. i

A plate 20, having a right angled flange portion 21 to extend over the joint between adjacent bars, has its main portion disposed in front of the joints as best seen in Figs. 1 and 5. 7

These plates contain the elongated narrow vertical openings 22, 23, 24, equal in length to the width of the projections 18, 19, and having between them ribs 25, 26.

The bar extensions 18, 19 are passed outwardly through the side openings 22, 24 and thereafter curled reentrant-ly to encircle the ribs 25, 26. and pass through the center opening 23 in intimate contact, forming eyes 18, 19, as by making forcible contact with a block as indicated at 27 in Fig. 3, constituting a double hinge joint in connection with the plate.

It is to be noted that these hinges have their eyes turned inwardly, thus avoiding danger of being opened or damaged by c011- tact with polishing wheels, the hinges permitting the bars to be swung inwardly at an angle until the ends of the bars make contact.

Not only do the plates present an ornamental effect, enhancing the appearance of the frame, but completely cover the joint, obscuring its construction.

While certain preferred embodiments of this device have been shown and described, it will be understood that changes in the form, arrangements, proportions, sizes and details thereof may be made without departing from the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent, is

1. In a collapsible bag frame having anected at their outer extremities, a plate at plurality of bars arranged in opposed paired relation, the outer bars being hingedly connected at their outer extremities, a plate at the abutting ends of said bars, said plates being shaped to produce three slots having two connecting ribs therebetween, and curled extensions on each of the abutting ends of said bars to pivotally encircle appropriate ribs in the adjacent plates.

2. In a collapsible bag frame having a plurality of bars arranged in opposed paired relation, the outer bars being hingedly conthe abutting ends of said bars, said plates being shaped to present a pair of parallel spaced ribs having openings at their outer sides and therebetween, and extensions on said bars to pass through the openings and curl around the adjacent ribs to form hinges, the ends of said extensions being disposed below said plates.

This specification signed this 19th day of January, 1926.
